dÄHLer Competition Line AG

dÄHLer Competition Line AG is the Swiss headquarters and authorised installer for dÄHLer performance parts, based in Belp (near Bern). They develop, sell and fit engine tuning, exhaust, suspension and trim upgrades for a range of vehicles.

The company operates a workshop for installations and servicing, provides technical consultation and is contactable by phone or email. Visits and work are handled by appointment during weekday business hours; Saturdays are by arrangement.

You’ll meet staff at a working tuning workshop where they inspect your vehicle, recommend dÄHLer parts or software and carry out installations and calibrations.

What you'll do:

• Initial consultation and vehicle inspection to confirm compatibility and aims.
• Demonstration of available parts (exhausts, ECU maps, cosmetic trim) and explanation of performance gains.
• Workshop installation or software flashing with post-fit checks and test drive if arranged.
• Paperwork: quotes, warranty/installation documentation and invoicing on completion.

Best way to experience it: book a phone or email appointment in advance, bring vehicle documents, and allow a half‑day for minor installs or a full day for extensive work or diagnostics.

• Visits and installations are by appointment; call +41 31 819 88 77.
• Official hours: Mon–Fri 08:00–12:00 and 13:30–18:00; Sat by appointment.
• The site is a working workshop—expect noise and vehicle movement.
• Bring vehicle registration and any existing service records for tuning compatibility.
